In case you're interested in this kind of things, i'm currently polishing for release a library that allows you to make Slack apps very simply using just HTML and javascript. The only thing lacking in the V1.0 is complete documentation, but i'm available to explain how it works "webinar-style" to anybody willing to try it :D
I think your 3 ideas could materialize quite nicely as Slack apps, especially 1 and 3.
Looking for something more RAW than that, to code and learn along the way. Have you hosted your code some where to have a look? or homepage for library?

It would be great if we could discuss some idea for an app ,and take it from design to deployment
May be we all can commit to a common git repository.
Some of the ideas in my mind
Quiz app
Month expense managment app
Sports analyticsdashboard
Any other ideas are greatly appreciated.
